  Described 
  from 
  nineteen 
  specimens 
  sent 
  me 
  by 
  Mr. 
  P. 
  F. 
  Creveconir, 
  

  

  which 
  he 
  took 
  among 
  leaves 
  iu 
  timber 
  at 
  Ouaga, 
  Kansas, 
  in 
  early 
  spring. 
  

  

  The 
  red 
  lines

  vertex

  the 
  very 
  obliqne 
  direc- 
  

   tion 
  of 
  the 
  inner 
  transverse 
  nerv- 
  

   ure 
  of 
  the 
  elytron, 
  the 
  parallel- 
  

   sided 
  and 
  very 
  narrow 
  apical 
  cell 
  

   of 
  the 
  elytron, 
  and 
  the 
  fact 
  that 
  

   these 
  specimens 
  were 
  taken 
  alcng 
  

   with 
  specimens 
  of 
  obliquH, 
  led 
  me 
  

   to 
  suspect 
  that 
  this 
  was 
  only 
  

   another 
  variety 
  of 
  that 
  si)ecies; 
  but 
  

   crevecaeuri 
  is 
  much 
  more 
  robust 
  

   than 
  oltliqiia. 
  and 
  the 
  characteristic 
  

  

  markings 
  of 
  the 
  former 
  is 
  so 
  constant 
  that 
  T 
  can 
  not 
  but 
  think 
  it 
  a 
  

  

  good 
  species.
